| 摘 要： | 下一代网络(NGN)与智能网原理上有许多相似之处,但是由于采用不同的实现技术体现出NGN优于智能网。通过NGN与智能网技术在目标和体系结构等方面的比较,特别是对目前传统智能网技术5个方面主要缺陷的分析,阐述了NGN中需要关注和加强研究的开放API、业务生成技术、业务支撑环境和网络演进技术等若干关键技术。特别是首次提出如何在NGN架构中继承已投资的智能网。

| Abstract: | Next generation of network(NGN) is similar to many aspects of intelligent network(IN) principles, but it works better than IN due to different implementation technologies. Through comparisons between the architectures and goals of NGN and IN, five major drawbacks appeared in current IN technology are analyzed. Then several key technologies on open API, service generation methodology and network evolution that need to be concerned and further investigated for NGN are proposed, especially regarding how to inherit the invested IN to build NGN architecture. |
